Sabina, dressed in tight athletic leggings and a tight top, picks up a colorful beach ball. She sits on it, bouncing slowly, then harder, teasing every patch of plastic. With each bounce, the pressure builds - and when she pauses, she brings the ball to her lips, taking a few playful breaths. With her bounces, She pushes the ball to its limits.... until it finally gives up with a loud, satisfying pop.
